Phawuo is an experimental monophonic virtual-analog synth with "dirty" oscillators. Good for bass sound and effects. New in version 3: - OSC support - AUv3 - Available for macOS (as a separate version); presets can be shared across devices It features: - Two special oscillators. Each one has two modes playing more rough (though antialiased waveforms with inharmonicity in higher pitches) or "cheezy" sound. Plays sawtooth / square waveform and is capable of pulse width modulation. - distortion and feedback ring modulation for each oscillator - 24 dB/octave state-variable filter (LP-BP-HP) - two ADSR envelopes for amplitude and filter - LFO to modulate the frequency and pulse width of oscillators' waveforms - Effects section: two channels of delay + frequency shifter with feedback with some flexible routing. Also includes basic reverb - Precise parameter editing: tap and hold finger on the slider. - Audiobus support. Now you can stream live audio directly to other Audiobus-compatible apps! See http://audiob.us for more information. - Inter-App Audio support - Background audio support: enabled when connected to Audiobus and user switchable otherwise. - CoreMIDI support - virtual midi input
Sparkle
Transform audio by transferring the temporal structure of one sound to another while preserving spectral properties. Create unique sound transformations with advanced spectral hybridization algorithms. Ideal for musicians and sound designers seeking innovative audio manipulation.
- Spectral hybridization
- Envelope preservation
- Phase-sync processing
- High-quality sound transformations
- Temporal structure transfer
- Spectral property preservation

Sparkle is a tool for advanced spectral hybridizations made of several algorithms that operate on frequency domain. By means of envelope preservation and phase-sync processing it can creates high-quality sound transformations. The basic idea is to transfer the temporal structure of a sound (source) onto another sound (target) of which the spectral properties are preserved. Simply put, you can take a voice and make it sing a Beethoven’s symphony!
